18. Communication
Th
e relay supports three diff erent communication
protocols: IEC 61850 , DNP3.0 Level 2+ and
Modbus®. Operational information and controls
are available through these protocols. Unique
communication functionality, for example, peer-to-
peer communication between relays is available via the
IEC 61850 communication protocol.
Th
e IEC 61850 communication implementation
supports all monitoring and control functions.
Additionally, parameter setting and disturbance fi le
records can be accessed using the IEC 61850-8-1
protocol. Further, the relay can send and receive
binary signals from other relays (peer-to-peer
communication) using the IEC61850-8-1 GOOSE
profi le, where the highest performance class with a
total transmission time of 3 ms is supported. Th
e relay
can simultaneously report to fi ve diff erent clients -
maximum fi ve IEC 61850-8-1 clients, maximum fi ve
Modbus clients and maximum one DNP3.0 Level 2+
client with total number not exceeding fi ve.
All communication connectors, except for the front
RJ45 connector, are located in the back of the unit
on the left most card slot. Th
is slot remains in the
case when the drawout unit is removed eliminating
the need to disconnect communication connections.
Th
e relay can be connected to an Ethernet-based
communications network via a copper RJ45 (100Base
TX) or fi beroptic LC (100Base FX) connector or
serial network via the RS-485 option that provides one
4-wire or two 2-wire ports.
Modbus over TCP/IP is supported with the Ethernet
communications option selected. Besides standard
Modbus functionality such as status and control
operations, the relay supports retrieval of time-stamped
events, uploading of disturbance fi les and storing of the
latest fault records. For the Modbus TCP connection,
a maximum of , fi ve clients can be connected to the
relay simultaneously.
DNP3.0 Level 2+ over TCP/IP is also supported with
the Ethernet communications card option. Another
serial communications option off ers programmable
RS-232 or RS-485 and fi ber-optic (ST) serial ports.
Status and control, including breaker trip/close
control, operations are supported in the Level 2+
implementation.
Optional serial (RS-232/RS-485) communication
interfaces are available that support user programmable
protocols of DNP3.0 Level 2+ and Modbus RTU/
ASCII. All serial communication card options include
an Ethernet communications port and an IRIG-B
port for dedicated time synchronization network
connections.
Th
e relay supports the time synchronization with a
time-stamping resolution of +/-1 ms:
